PicoScope 6 (6.4.28) with a 4000 series DSO will allow you to look at Frequency up to 20kHz. I don't know the operating range of the sensors you speak, so this may or may not allow you to test to the upper limit of the sensor. Graphing frequency, however, would lend itself better to testing for a skewed sensor.
HTH. Later, Matt.
